Is it my ancient, finicky pc (10/11 yr old IBM Aptiva) or is it the site? I don't know, but maybe you do.

My pc freezes whenever an "almost pop-up" occurs. By "almost pop-up" I mean that despite activating Googles' pop-up blocking mechanism I sometimes but not always, still get the outer frame and a brief glimpse of the header of the pop-up. The whole site then freezes with the almost pop-up frame. When I attempt to end the task through close program, it freezes as well. I can go into my yahoo or sympatico and then come back into pets.ca but in order to get rid of the first pets.ca (or access any links to external websites while in the second pets.ca) I have to shut down using control-alt-del. I should note that this freezing also happens when I allow pop-ups. This only happens with pets.ca !

It has happened to me too. Not every time I log in but frequently. I don't have a new computer by the longest stretch of the imagination but it's OK for now. Running windows me. I often find that I freeze up more often when logging off a forum so I tend to just stay logged in even when I'm not on that site.

I would suggest that it's the Aptiva (wow I haven't even heard that name in a long while)

I suspected that would be the verdict. I just thought it's curious that I don't have this issue elsewhere. Personally, I think the thing my finicky old gal can't handle are the ads you have at the top of the screen. It seems the more animated they are, the more I have difficulty.

I'm sorry for the trouble mumx3 - it's a balance.
The ads help pay the costs....
Unfortunately (and this is NOT a cop-out on my part) I think you're having a lot of extra trouble because you are using a really old OS on an older computer. Most people can block the ads or ignore them without too much hassle...
